# SRFI 143 - Fixnums
|
|
|
|
This SRFI describes arithmetic procedures applicable to a limited range of exact integers only. These procedures are semantically similar to the corresponding generic-arithmetic procedures, but allow more efficient implementations.
|
|
|
|
See the [SRFI document](http://srfi.schemers.org/srfi-143/srfi-143.html) for more information.
